ABSTRACT:
A process is disclosed for forming a thermoplastic structure on the exterior surface of the heated mold form. A mold is heated to approximately two times the melting temperature of a thermoplastic material and particulate thermoplastic material then sprinkled onto the exterior surface of the heated mold. An adhesively bondable material may then be added to the semi-molten thermoplastic material structure. The mold is then cooled and the resulting thermoplastic structure removed.
An apparatus for practicing the above process comprising a mold form, heating system, and particulate thermoplastic material dispensing system is also disclosed.
